The next three questions are all related:You are testing the null hypothesis that the outcome of a dihybrid cross conforms to a 1:1:1:1 ratioresulting from a cross between a heterozygous individual (AaBb) and a homozygous recessiveindividual (aabb), and that any differences are due to chance.Part I: How many degrees of freedom are there?

The degree of freedom is a mathematical restriction that designates what range of values fall within…

Mendelian Genetics [6F.R]:Question 1 In rabbits, grey fur (G) is dominant to white fur (g) and black eyes (B) are dominant to red eyes (b). A male rabbit with the genotype GgBb is crossed with a female rabbit with the genotype ggbb. What percent of the offspring will have white fur and red eyes? Select one: 25% 50% 100% 0% 1000
In the common daisy, genes A and B control flower color. Both genes have a dominant allele (A or B) and a recessive allele (a or b). At least one copy of each dominant allele is required for flowers to be colorful instead of white. (Explain and Justify your answers) 21.1) Predict the genotypes and phenotypes of the F1 progeny of a cross between two white-flowered plants, one homozygous AA and the other homozygous BB. A) AA bb, white B) aa BB, white C) Aa Bb, colorful D) Aa Bb, white E) aa bb, colorful 21.2) Predict the phenotypic ratio of the F2 progeny of a cross between two white-flowered plants, one homozygous AA and the other homozygous BB. A) 3 colorful : 1 white B) 9 colorful : 7 white C) 9 white : 7 colorful D) 15 white : 1 colorful E) 15 colorful : 1 white 21.3) The inheritance pattern of daisy flower color provides an example of what type of gene interaction? A) additivity…

In human blood chemistry, the I gene directly determines ABO blood antigens and the H gene takes the H-substance precursor and makes the H-substance. IAIO Hh x IBIO Hh. Given the following cross, help me with the question please 17. What type of allele interaction is this, the influence of alleles at gene H versus those at gene I?A) dominance B) recessive C) incomplete dominance D) epistasis 18.

This question deals with Mendelian Genetics. Read each part carefully before you answer it. In the following questions, assume green pea pods are dominant over yellow pea pods. a) If a pea plant that is Heterozygous for pod color is crossed with a pea plant with yellow pods, what do you expect to see in the offspring (the f1 generation)? Specifically, what genotypes, what phenotypes, and in what ratios? (Use G for the green pod gene and g for the yellow pod gene.) (It is usually helpful to write out all the possible genotypes and give the phenotype for each genotype before answering the specific question.)
PRISCILLA TORRES Mendelian Genetics [6F.R]:Question 2 In fruit flies, red eyes (R) are a dominant trait and white eyes (r) are recessive. If a homozygous red eyed fly was crossed with a white eyed fly, what percent of the offspring would be homozygous recessive? Select one: 50% 100% 25% DELI
A sex-linked recessive allele rg causes a red-green colorblindness in humans. A normal woman whose father was colorblind marries a colorblind man. A. What genotypes are possible for the mother of the colorblind man? B. What are the chances that the first child from this marriage will be a colorblind boy? C. Of the girls born from this union, what proportion can be expected to be colorblind? D. Of all the children of these parents
A cross was performed using Drosophila melanogaster involving a female known to be heterozygous for both ebony body and sepia eyes and a male known to be homozygous for both of these recessive traits. The following data was produced from the cross. Test these data to determine if they are significantly different from the expected phenotypic ratio. Remember to use the 5% level of significance Wild eye Wild body – 102, Wild eye Ebony body – 94, Sepia eye Wild body – 100, Sepia eye Ebony body – 93. Your answer should include the hypothesized cross in genotypes, the Chi-squared value, the critical value and whether you reject or do not reject.
In rabbits, white coat color (CW) and black coat color (CB) are codominant, and both of these alleles are dominant over albino (c); heterozygotes (CWCB) are spotted. Consider a cross between a heterozygous black-coated rabbit and a homozygous white-coated rabbit.
You are studying a gene that controls ossicone (horn) length in giraffes. The wild type long-ossicone allele (L) is dominant to the mutant short-ossicone (I) allele. However the L allele is only 60% penetrant. You cross a long-horn heterozygous giraffe to a short- horn giraffe. What phenotypic progeny classes do you expect and at what frequencies?
